-Package tracing is a library that provides distributed tracing to Go applications. It offers features such as collecting performance data of an application, identifying where requests are spending most of their time, and segmenting requests. It supports exporting traces to 3rd\-party services such as Jaeger, Zipkin, Opentelemetry, and NewRelic. Go\-Coldbrew Tracing helps developers quickly identify issues and take corrective action when performance bottlenecks occur.

+Traces are created using OpenTracing APIs and exported via the configured global tracer \(opentracing.GlobalTracer\). The core package configures this tracer at startup — typically an OpenTelemetry bridge that sends traces to any OTLP\-compatible backend \(Jaeger, Grafana Tempo, Honeycomb, etc.\) or New Relic.
